Product Description:

Abrasive Black Silicon Carbide powder 98.5% SIC

1.Structure of Silicon Carbide Description

Black Silicon Carbide is produced with high temperature in a electric resistant furnace from a mixture of quartz sand and petroleum coke.

Black silicon carbide is typically used for working on cast iron ,non-ferrous metals, stone, leather, rubber, and other materials which requires sharp cutting characteristics. The mineral is also used widely as a refractory material and metallurgical additive. 

2.Main Features of the Calcined Bauxite

Its hardness is between that of fused alumina and synthetic diamond and mechancial intensity of it is also greater than that of fused alumina. It is brittle and very sharp and  has a certain degree of electrical and heat conductivity.

3.Main usage of the Calcined Bauxite

1.Grinding non-ferrous materials, rock, stone, leather, rubber, finishing tough and hard materials

2.Bonded abrasive tools, lapping and polishing

3.Widely used as a metallurgical additive and refractory material

Q:What antioxidant will be used in refractories?
Antioxidant: Si, Al, Mg, Ti, AlSi, AlMg, SiC, TiC, ZrC and these metal nitride, boride. Sintering agent: different mechanism, Cr2O3 to promote the sintering of alumina;CaO/MgO style promote ZrO sintering;Siliceous ramming material to add boron bottles, magnesia coating and clay, etc.
Q:The manufacturing technique of refractory material
The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%~85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
Q:What is refractory brick?
Capability1. Refractory brick is also known as firebrick. It is faint yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
Q:Current development status of qualitative refractory materials.
Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.
Q:Who knows about the B-level fireproof insulation materials?
Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
Q:What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
Q:How to make use of waste refractory materials whose main elements are alumina and mullite?
Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Domestic boric acid is practicable. The ratio is to determined combined with material, steel (iron) species, smelting temperature, current and other factors
Q:What are the requirements for the performance of refractory materials?
Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.
